Issue raised by staff running macOS Ventura (13.6.6) w. Microsoft 2021.
At the time of this issue (not being able to print more than one copy), the Konica Minolta Bizhub C308 printer driver had been freshly installed without configurations/modifications.
All basics were tried: all printers removed, Excel & Word updated to latest, full computer restart, followed by re-adding printer w. drivers and testing.
Issue continued with Microsoft Excel only.
Microsoft Word was able to print multiple copies, as well as both Acrobat and Preview or any other test app (eg Chrome).
Employee needed to return to work, so I went to test on my system: macOS Sonoma (14.5 -latest), Microsoft Office 365 (latest/all updates), with the latest Konica Minolta drivers and the issue was recreated.
I use Excel in a very basic way, so there are no add-ons, preference changes or such to consider. The computer was also fully restarted. The file used for testing was a newly created spreadsheet with just the word: test.
Nonetheless Microsoft Excel was reset via the Terminal w. the following command:
$ defaults delete com.microsoft.Excel
There should be no permission issues, but I went ahead and saved the test file to Desktop. Restarted the unit, and tried again: Issue persisted.
As noted by everyone else, other apps appear to print multiple copies without an issue, all except for Excel.
TIA for any suggestions.
